Adding Custom Post Types To Your Search Query
Jan 06
All you need to do is create a function, which can be add to your functions.php file. This function checks if the $query variable is the search query $query->is_searchpasses the $query and then sets the post types which should be searched using the queried keyword you entered in the form, then returns what the $query should search within.
// Define what post types to search
function searchAll( $query ) {
if ( $query->is_search ) {
$query->set( 'post_type',
array('post','page','feed','custom_post_type1',
'custom_post_type2', 'custom_post_type3',
'custom_post_type4' ));
}
return $query;
}
// The hook needed to search ALL content
add_filter( 'the_search_query', 'searchAll' );
